I have downloaded a RAR file from the following location, to be (manually) installed to Eclipse (Helios). How can I perform the manual installation?

From their website (http://www.sqlexplorer.org/):
Eclipse Plugin
Download
Download the Eclipse SQL Explorer plugin and extract the zip file in your eclipse directory (requires Eclipse 3.3 or better). After restarting eclipse with the -clean option, a new SQL Explorer perspective should be available.
Eclipse Update Site
You can install and update Eclipse SQL Explorer via the eclipse update mechanism. The update site for Eclipse SQL Explorer is http://eclipsesql.sourceforge.net/
I always go for the update site option if they present it, it's easier and lets you do updates easily. To use the update mechanism just select Help > Insall New Software... then enter the update site, press Add and go through the wizard.
